Keep an eye out - Mopar Performance ECU #'s

Keep an eye out when picking through the XJ pile at your local boneyard...

The Mopar performance ECU doesn't have the same number on it as it is sold under! Just a quick FYI for all that if you have Bendix ECU marked as P4532129 then you actually have a Mopar Performance Computer for 87 - 90 Renix 4.0L's which was (for some reason) sold under P4529334.

Don't ask me. Probably the same Daimler Chryackhead that decided to put metric and sae bolts on the one bracket also decided to sell part A under number B...

what kind of gain will they produce.

Don't have a dyno sheet for one. Basically - Improved timing & fuel map. Think of it as a prehistoric 'hot chip'... only ya replace the whole ECU since the Renix ECU isn't easily upgraded.
